Taipei, May 28 (CNA) A cat that escaped Taiwanese airport security checks and made its way to South Korea in its owner's check-in luggage was brought back to Taiwan Wednesday, this time in a pet travel crate. Upon arrival at Taiwan Taoyuan International Airport, the owner Chin You-hao said he was not guilty of abusing the animal, as speculated, because he was not aware that the cat had hidden itself in his luggage. The pet, which Chin has had for six years, was discovered in his check-in luggage by South Korean inspectors when he arrived there May 24 but had not been spotted by security personnel at Taiwan's main international airport. While he expressed sympathy for the luggage inspector who was disciplined over the incident, Chin said the airport's security personnel should have found the cat, which he said had sneaked into his suitcase. Chin said he had packed his clothes in the left side of the case and right side was empty. That is where the black cat decided to hide, he said. During his three-day stay in South Korea, he spent a lot of time dealing with issues related to the cat, he said, adding that he will double check his luggage next time he is traveling. Upon arrival at the airport in Taiwan Wednesday in a proper travel crate, the cat was put into quarantine for 21 days at a facility in Taoyuan County. According to Taiwan's Aviation Police Bureau, the luggage inspector at the Taoyuan airport noticed an orange object on the X-ray screen but did not order a manual check of the suitcase because he did not identify it as a dangerous item. The bureau, meanwhile, said it has decided to assign senior personnel to screen checked luggage and inspect suitcases manually when necessary. It was the second case of lax security at the Taoyuan airport in recent weeks. A Japanese national traveling to the Philippines was found on arrival to have two gallons of diesel fuel stored in his checked baggage recently. (By Bien Chin-feng and Elaine Hou)
